Filed: 1988-11-08
Abstract: PURPOSE: To minimize the disturbance of the system by forming an asymmetry signal to detect the instantaneous asymmetry of the voltage system of a three- phase AC system, and modulating a control angle with this signal. CONSTITUTION: A converter RR is connected between a three-phase AC system and a DC circuit, and has a controller ST where the control angle a o is decided in advance and a voltage analyzer DET. Then, the current target value i'd is supplied to a voltage adjuster DI together with an actual value id within an adjusting element CR1 on one hand, and a suitable signal is added to the output signal of a current adjuster CI for compensation of inductive voltage drop by a proportional element PP on the other. Furthermore, one minimum value selecting circuit min selects the signal, and supplies it to a divider DIV among the adjusting elements CR2. This divider DIV is connected to a system voltage analyzer DET, and the output is inputted into a linearizing element LIN2 through a run up generator HG, and it forms an ignition pulse αi with a controller ST.

IPC: H01L23/28
Filed: 1990-10-22
Abstract: PURPOSE:To attain a high heat radiate power and high reliability by a method wherein a semiconductor element chip is supported from above and below by metal support plates and sealed with resin. CONSTITUTION:An element 10 is mounted on a lower-side support plate 17, a lead frame is superposed on the lower-side support plate 17 and the support plate 17 is fixed to an inner lead 11. Next, the inner lead 11 and an electrode on the element 10 are wire-bonded, and after a film 14 is stuck on the element 10, an upper-side support plate 16 is fixed to the inner lead 11. Lastly, an assembly thus prepared is sealed with resin. The heat generated in the element 10 flows very well to the support plates 16 and 17 and thus a heat-radiation property is improved remarkably. Besides, the plates have an effect that a thermal stress generated by the shrinkage of the resin 18 after molding is checked from acting directly on the element 10, and thus prevent the damage of the element 10.

Abstract: PURPOSE: To improve safety by judging the presence or absence of disconnection and contact fusing of a lead switch, opening and closing a door at a low speed, stopping it, and informing an abnormality to the outside when the abnormality occurs, and opening and closing the door at a high speed at the time of normal operation. CONSTITUTION: When a close origin switch RDS is off after power supply is turned on, a door is opened and closed at a low speed when a human body detector MS is turned on, and it is judged that a disconnection occurs if the above-mentioned operation is repeated several times irrespective of a sufficient stroke. When the close origin switch RDS is normal, the human detector MS is turned on without fail by one time low speed opening and closing loop. Moreover, when the close origin switch RDS is on, the door is opened at a high speed when the human detector MS is turned on. However, if an ON state of the close origin switch RDS is continued, it is judged that contact fusing of the switch occurs. When these abnormalities are not detected, the door is opened and closed at a high speed.
